Fluoroboric acid or tetrafluoroboric acid (archaically, fluoboric acid) is an inorganic compound with the chemical formula [H⁺][BF₄⁻], where H⁺ represents the solvated proton. The solvent can be any suitably Lewis basic entity. For instance, in water, it can be represented by H₃OBF₄ (oxonium tetrafluoroborate), although more realistically, several water molecules solvate the proton: [H(H₂O)ₙ⁺][BF₄⁻]. The ethyl ether solvate is also commercially available: [H(Et₂O)ₙ⁺][BF₄⁻], where n is most likely 2. Unlike strong acids like H₂SO₄ or HClO₄, the pure unsolvated substance does not exist (see below).
